Why is J.K. Simmons Getting Terrifyingly Ripped for the Justice League Movie?

Former Marine Aaron Williamson is a fitness pro whose clientele includes Dwayne Johnson — someone whose physique has played a huge role in his career — and apparently, uh, J.K. Simmons, the 61-year-old Oscar winner who is working out hard for his role as Commissioner Gordon in Zack Snyder’s now-filming Justice League movie.

Why Simmons — who was already notably buff in Whiplash, as evidenced in the top image — has decided to get so much more ripped for Justice League is a bit of a mystery. Will he have a fight scene? A beach scene? A scene in which he hosts a one-armed push-up contest?
